I entered the Linux Mint 19.3 Driver Manager and tried the Driver xserver-xorg-video-nouveau (because browse google-chrome was not working properly. It was closing abruptly). He accepted the exchange and after restarting notebook it booted normally, but the laptop's webcam did not work longer. When I tried to go back to the proprietary Driver, I opened again the Driver Manager, but this time it came back empty with no option of drivers to choose.
How could I fix this? The driver that was installed is Nvidia 435,21-0ubuntu0. 18.04.2. My notebook model is the Acer Nitro 5 AN515-52-5771 MFG Date:1910, 15.6", Intel Core i5 - 8300H. The Video Card is NVIDIA Corporation: GP107M [GeForce GTX 1050 Mobile].
